[ENGLISH-SUBTITLE] FSDSS-774 When I called a big-breasted delivery health girl, I ran into my strong-willed younger female boss... I made her my personal masochistic milk pet. Mami Mashiro 12,080 93

I joined the company mid-career and I'm not used to the job, so I'm always being told off by my aggressive younger female boss, and I'm feeling really resentful. One day, I went to a delivery health service to relieve stress, and I had an unexpected encounter with my female boss. Now that I know her weakness, I'm in a position where I'm facing off against my embarrassed boss. As if to get rid of all the resentment I've had up until now, I do whatever I want with her. I make her my own personal flesh toy that I can use whenever I want.
